I have a 1987 Chevy S10 with only 81500 miles on it.It is a 2wd 4cyl automatic 2.5 fuel injected engine.I just have a few repair questions and hope you might have answers for me.

How do I know if my MAP Sensor is bad?

Does my throttle body have a Mass Airflow Sensor?

It doesn't have a MAF sensor-You asked about the MAP sensor is it bad are you getting a DTC 33/34 if not its doing its job.

Try using a jumper wire between A and B then count the flashes- for a code 12 flash pause then flash flash.
